Your Xperia™ from Sony runs on the Android platform. Android devices can perform
many of the same functions as a computer and you can customize them to your own
needs. For example, you can add and delete applications, or enhance existing
applications to improve functionality. On Google Play™, you can download a range of
applications and games from a constantly growing collection. You can also integrate
applications on your Android™ device with other applications and with online services
that you use. For example, you can back up your contacts, access your different email
accounts and calendars from one place, keep track of your appointments, and engage in
social networking.
Android™ devices are constantly evolving. When a new software version is available and
your device supports this new software, you can update your device to get new features
and the latest improvements.
Your Android™ device is pre-loaded with Google™ services. To get the most out of the
provided Google™ services, you should have a Google™ account and sign in to it when you
first start your device. You also need to have Internet access to use many of the features in
Android™.
New software releases may not be compatible with all devices.
•Remove the back cover, then insert the micro SIM card into its slot with the gold-
colored contacts facing down.
You must use a micro SIM card for your device to work correctly. Some standard-sized SIM
cards allow you to detach an integrated micro SIM card. Once you detach the micro SIM card
from the standard-sized SIM card, you cannot reattach it and use the standard-sized SIM card
again. If you do not have a micro SIM card, or if your current SIM card does not contain a
detachable micro SIM card, contact your network operator for information on how to collect or
exchange your SIM card.
To remove the micro SIM card
1Turn off your device.
2Remove the back cover.

services from your device as well as from a computer.
Having a Google™ account is key to using a range of applications and services with your
Android device. You need a Google™ account, for example, to use the Gmail™
application in your device, chat with friends using Google Talk™, and synchronize the
calendar application on your device with your Google Calendar™. You also need a
Google™ account to download applications and games, music, movies, and books from
Google Play™.

Battery
Your device has an embedded battery.
Charging the battery
Your battery is partly charged when you buy the device. It may take a few minutes before
the battery icon appears on the screen when you connect the charger cable to a
power source, such as a USB port or a charger. You can still use your device while it is
charging. Charging your device over a long period of time, for example, overnight, does
not damage the battery or the device.
The battery will start to discharge a little after it is fully charged and then charges again after a
certain time when the charger is connected. This is to extend battery life and may result in the
charge status showing a level below 100 percent.
1Plug the charger into a power outlet.
2Plug one end of the USB cable into the charger (or into the USB port of a
computer).
3Plug the other end of the cable into the micro USB port on your device, with the
USB symbol facing up. The battery status LED lights up when charging starts.
4When the battery status LED is green, the device is fully charged. Disconnect the
USB cable from your device by pulling it straight outward. Make sure not to bend
the connector when removing the cable from the device.
If the battery is completely discharged, it may take a few minutes before the LED lights up
after you connect the charger cable to a power source.

Improving battery performance
The following tips can help you improve battery performance:
•Charge your device often. This will not affect the lifetime of the battery.
•Downloading data from the Internet is power consuming. When you're not using the
Internet, you can save power by disabling all data connections over mobile networks.
This setting does not prevent your device from transmitting data over other wireless
networks.
•Turn off GPS, Bluetooth™ and Wi-Fi® when you don't need these features. You can turn
them on and off more easily by adding the Quick settings widget to your Home screen.
You do not need to turn off 3G.
•Use the Extended Standby Mode setting to minimize battery consumption when the
screen is inactive.
•Set your synchronization applications (used to synchronize your email, calendar and
contacts) to synchronize manually. You can also synchronize automatically, but increase
the synchronization intervals.
•Check the battery usage menu in your device to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
applications, such as YouTube™. Some applications downloaded from Google Play™
may also consume more power.
•Close and exit applications that you are not using.
•Lower the screen display brightness level.
•Turn off your device or activate the Airplane mode setting if you are in an area with no
network coverage. Otherwise, your device repeatedly scans for available networks, and
this consumes power.
•Use a Sony original handsfree device to listen to music. Handsfree devices demand less
battery power than your device's own loudspeakers.
•Keep your device in standby mode whenever possible. Standby time refers to the time
during which your device is connected to the network and is not being used.
•Disable any live wallpaper.

in standby mode. You can still receive phone calls, and text and multimedia messages.
Once the screen becomes active again, your phone exits standby mode and all paused
functions are resumed.

Using the touchscreen
A protective plastic sheet is already attached to the screen of your device when you buy
it. You should peel off this sheet before using the touchscreen. Otherwise, the
touchscreen might not function properly.
When your device is on and left idle for a set period of time, the screen darkens to save
battery power, and locks automatically. This lock prevents unwanted actions on the
touchscreen when you are not using it. You can also set personal locks to protect your
subscription and make sure only you can access content on your device.
